status":406,"error":"Not Acceptable" message":"Payment declined: amount exceeds 100.00

While running load-tests, I see lot of error responses in front end logs -

Order response: {"timestamp":1543518975262,"status":406,"error":"Not Acceptable","exception":"works.weave.socks.orders.controllers.OrdersController$PaymentDeclinedException","message":"Payment declined: amount exceeds 100.00","path":"/orders"}
Order response: {"statusCode":406,"body":{"timestamp":1543519009697,"status":406,"error":"Not Acceptable","exception":"works.weave.socks.orders.controllers.OrdersController$PaymentDeclinedException","message":"Payment declined: amount exceeds 100.00","path":"/orders"},"headers":{"x-application-context":"orders:80","content-type":"application/json;charset=UTF-8","date":"Thu, 29 Nov 2018 19:16:49 GMT","x-envoy-upstream-service-time":"18","server":"envoy","connection":"close","transfer-encoding":"chunked"},"request":{"uri":{"protocol":"http:","slashes":true,"auth":null,"host":"orders","port":80,"hostname":"orders","hash":null,"search":null,"query":null,"pathname":"/orders","path":"/orders","href":"http://orders/orders"},"method":"POST","headers":{"accept":"application/json","content-type":"application/json","content-length":232}}}

Where is the amount populated while making calls from load-test microservice? and how to fix these errors?
